Prevalence and predictors of cardiac troponin elevations following exercise: a systematic review, meta-analysis, and meta-regression
- Systematic review, meta-analysis and meta-regression
- random-effects
- multilevel mixed-effects meta-regression
- cubic spline models
Authors' conclusion
cTn elevations are common following exercise, most often with high-sensitivity assays and cTnT measurements, particularly in endurance sports lasting 3-6 hours.
Study context
- Population
- Athletes after exercise (78% male; mean age 44.9 years; median exercise duration 4.2 hours)
- Participants
- 7,289 athletes · 129 studies
- Outcome
- Prevalence of post-exercise cardiac troponin (cTn) elevations above the assay-specific URL
Pooled result
As reported in the abstract
cTn above URL after exercise
Prevalence of cardiac troponin (cTn) above upper reference limit (URL) after exercise (95% CI 31-42%); between-study range 2-98%, extreme heterogeneity
36%
